A bag contains 6 red balls and 7 green balls. You plan to select 4 balls at random. Determine the probability of selecting 4 green balls.

Assuming draw without replacement of the balls, we have:

1. Selection 1: 7 green out of 13 balls
2. Selection 2: 6 green out of 12 balls
3. Selection 3: 5 green out of 11 balls
4. Selection 4: 4 green out of 10 balls

Since each draw is independent, we multiply each probability of green:
P(GGGG) = 7/13 * 6/12 * 5/11 * 4/10
P(GGGG) = 840/17,160
P(GGGG) = 0.05
